A recent patent application from Google describes the way they make use of previous query for influencing the advertisements that pop up during a search.

The patent describes the ways in which the search engine decides the relation between a current and previous query. This is used to determine whether they should encourage ads that support both queries.

The patent clearly describes the way they expand the search query for matching with various advertising keywords. This happens when there is no previous query from the searcher. In such a case, the search engine will look for related words and will perform query broadening.

Ads are shown mostly based on the words which relates to the particular query. This is obtained through getting information through clustering tools and various other systems.

This patent describes how search results could be expanded through a web search. This indicates the instance during which there are no results for any query entered by the user. Google will also look at various overlapping words in those queries which happened during the search, for displaying results to users. Previous queries in this way will relate to the sponsored links which are highlighted on the top of the pages which are shown as results.

A recent patent from Yahoo describes in detail how people or users can help in the crawling of web pages. This patent is known as the automatically fetching patent and will come up with details of how a user or site interaction could be used to help the search engine crawling program.

The activities which are involved and addressed include the webmaster training the crawler of how to find out the pages which are indexed in their website. A human reviewer is teaching the crawler of how to find out the pages. The content subscriber will show the crawling program, the information that would be subscribed to and updates will be sending about it.

As per this patent, the search engine will allow people to teach the web crawling program. This will help in the navigation of pages of the website. This will be particularly more useful in accessing web pages which have java script links and those pages which are accessible only through various selections. Pages which are accessible through inputting text into forms can also be navigated with the help of this patent implementation.

The patent find application when search engines find difficulties in crawling pages which could be due to java script links.

Search engines care much about the presence of spam in their search results. SEO optimization cares a lot about technical as well as informational base for the websites so that users will get all relevant information and data from the search engines. Microsoft has come up with a recent patent application stating the classification system that helps search engines in working with the spam. This will help the search engines to optimize those results which are not useful for the particular queries. This system normally works on the basis of the comparing features which will search queries and other features of the web pages. In fact, this helps to rank the pages better for the queries as well.

When the pages that is more relevant for the search is displayed, those pages which are spam are less likely to be displayed. The patent describes that, there are various reasons for keeping from displaying the spam pages along with the web page results of searches. The most important reason is that when the spam pages increase, users might switch to other search engines. Another reason is that websites might start using spamming techniques to increase their ratings over the spam pages.

After their attempt to a little touch up, Google analytics offers an important upgrade. They are offering a better approach to:
• AdSense integration
• Motion Charts
• advanced segmentation
• API
• custom reports
• updated user interface

Though being hailed as an upgrade, the great news is it’s free. These tools can be used by all Google analytics users. The idea behind this move is to make the expensive and difficult to use tools gain larger acceptance. In this new approach, they are free and easy to use. This adsense integration lets you link your adsense and analytics account after which you can view all adsense data. Now you can evaluate and watch your account closely and determine changes in:

• total revenue
• impressions
• clicks
• click-through ratio
• revenue per day,
• revenue per hour
• revenue per page
• per pages profitability
• revenue per referral
• data on sites that bring in profitable traffic

If you’re wondering how to get around to using these tools which may seem a little complicated, there’s good news. Google has made available videos to aid users in their quest to master the use of their integration tools. Things will take a while to be used by all but the beginning is here.

As a webmaster, you want to find the best sources to back link and populate. As a surfer, you obviously want to find just what you need within the shortest possible time, rather than have to open multiple pages on a new tab just trying to locate what you need. One would think what a waste of time. Of course all the information you need is online, but do you know how to look at it. Make search engines work for you and reduce the time spent looking for what you need.

When you key in keywords, instead of typing in multiple keywords that will result in too many finds, use your target search terms in quotes. As such, if you are looking for SEO news in the business niche, type in “SEO news business”, instead of SEO news business, because the results will be far too many for the latter.

If you are looking for information on light but not electric supplies, your search input should look like light -bulb. Of course, you’ll have to use average intelligence to get to the right search times but this will save you a lot of time and guarantee a larger degree of search oriented finds rather than random finds.

It is generally heard that when the number of pages hold by the search engines increases, the chances that they cant provide the best results for the customers are high. It means that, as the log with the search engines increases, the best pages obtained in exchange of the queries will be less in number.

The uncertainty involved in the chances of losing the amount of information content missed by a person looking for results are known by the term entropy. The entropy involved in the search performed by search engines is not that high as we imagine. The search engines can well predict the information and the pages which are more relevant to the person who is making the search.

Since most of the search engines gain more information through the personalization, the entropy is decreased even further. This will make the work of search engines even easier while making a query for the word entered by the user. If there is not much information about the interests of the person making search, they will take personal data like the membership of the individual to understand the kind of information he will be looking for. Location information through IP address is also used as a way to reduce the entropy.

Right from the beginning of search engine optimization, you might have heard the relevance of anchor text in page ranking. Recently Yahoo obtained the patent that describes the relevance of this anchor text. The patent is relatively old and dates back to 2002, but it has some relevant information on using of anchor text. This patent describes the method adopted by search engines in using the anchor text for indexing.  

This clearly explains the information on how pages will be ranked by search engines for anchor texts which are not directly present in their content, but rather are present in the links which refer to these pages. The process used is a simple breaking up of the anchor text into tokens after they are collected from various pages pointing to the same page through links.  

Then these tokens are given weights which are evaluated and the page which has the highest threshold weight will be considered for indexing by the search engine. The weight calculation is done by some simple formulas which determine the frequency of the token in the anchor text of the link pointing to the page. This also determines the frequency of the token in the search engine index.
